Please answer & explain 22-25
22. Pressure is created when a gas is compressed and the temperature is decreased proportionally b) gas particles collide with the sides of their container more gas particles are added and the volume is increased proportionally gas particles are removed and the volume stays the same 23. because In response to Boyle's law, the pressure of a gas increases as the volume a) decreases; the gas particles strike the walls of the container more often...

A gas cylinder containing carbon dioxide, CO2, 85% by volume, and nitrogen, N2, 15% by volume has a volume of 2.2 m and is kept at a temperature of 20°C. You may assume the gas mixture is ideal. 0 Calculate the pressure in kPa in the cylinder when it contains 50 kg of gas. [2 marks] After a certain amount of gas has been used, the pressure decreases by 150 kPa. Calculate the mass of gas used. [2 marks] (b)...

Let us first examine the behavior of an ideal gas when we force the volume to be a value of our choosing. We can examine how changes to the absolute temperature and number of moles affect the pressure of the gas particles (by selecting pressure with Rspd such that pressure cannot be controlled). Assume that 0.03 mol of helium at a temperature of 275.00 K occupy a volume of 1.40 L. Use the Run Experiment tool in the Simulation to...

A spray can containing a propellant gas at twice atmospheric pressure (202 kPa) and having a volume of 119.00 cm is at 27°C. It is then tossed into an open fire. (Warning: Do not do this experiment; it is very dangerous.) When the temperature of the gas in the can reaches 195°C, what is the pressure inside the can? Assume any change in the volume of the can is negligible. SOLUTION Conceptualize Intuitively, you should expect that the pressure of the gas...

Q2)
2) An automobile tire is filled to a gauge pressure of 196 kPa
when its temperature is 20°C. (Gauge pressure is the difference
between the actual pressure and atmospheric pressure.) After the
car has been driven at high speeds, the tire temperature increases
to 51°C.
(a) Assuming that the volume of the tire does not change, and
that air behaves as an ideal gas, find the gauge pressure of the
air in the tire.
(b) Calculate the gauge...
